Serured lo lhe ernuk enne -lby Ineens of Screws l() is n si ulionnry support` or plate -lf'l having :i eireuhlr [hinge #l2 filling over the extension :i on the frank ense. Rolutnhly mounted on the' flange `'l2 of the phit'e Al1 is a hollow Serew member -ll held thereon by lnenns of holle 'l-l having enlarged heads 45 hearing ngniusli the stepped porlion LG ol grooves 47' gnged hy Hpirnl threads; or longues lili) on the nut 37. rihe nut 37 is prevented from rotating on the screw member 43 by means of lugs 50 which extend into slots 51 in the flange 42 of the plate 41. The screw member 43 may be rotated on the iange 42 by means of an arm 52 formed thereon and connected at its outer end in any suitable manner to proper mechanism (not shown) for operating the same.

The operation of the device is as follows r-When the parts are in the respective positions shown in Fig. 1, with the engine driving the shaft 1 and liead 3, together with the disks 25, the pulley 10 is free from the engine shaft, the disks 25 being loose between the disks 23 as the dogs 30 are in inoperativeposition. That is, the dogs are in such a position that the inner ends of the dogs are nearer the shaft 1, thereby permit? ting the cam face on the outer end of the dogs to move away from contact with the inner disk 23 in which position the disks 23 and disks 25 are not in frictional contact. When it is desired to clutch the pulley 10 to the driving member or shaftl 1 and drive the belt 12, the arm 52 is moved in the direction of the arrow, Fig. 3, thereby turning the screw member43. The spiral grooves 48 in the screw member 43 cause the nut 37 to move into the positionshown in lFig. 2 as the spiral tongues 49 on the nut 37 are in engagement with the grooves 48 in the screw member 43, as clearly illustrated in Fig. 4. The lugs 50 being in the slots 51 in the flange 42 of the plate 41 prevent the nut 37 from rotating with the screw member 43. The ring 35 is carried forward with the nut 37 and moves under the inner ends of the dogs 30, raising the inner end of the dogs and causing the cam face on the outer end of the dogs to press the disks 23 and 25 into tight frictional engagement with each' other, thereby locking vthe pulley to the shaft 1. To release the pulley from the shaft 1, the arm 52 is moved to its original position and the respective parts return to the position shown in Fig. 1, permitting the engine' shaft to run free ofthe pulley and power transmission belt.

What I claim is 1. The combination` with a driving member and driven member, of means for frictional engagement therebetween, presser members carried on said driven member adapted to eng-age said frictional engagement means, a stationary member, a member rotatably and'non-slidably mounted on said stationary member, a member slidably and non-rotatably mounted on said stationary member, means connecting said rotatable and non-rotatable members, Jto-slide the non-rotatable member on rotation of said rotatable member and thrust means carried by said non-rotatable member,for engaging said presser members to move them into opreissen erative relation with said frictional engagement means on the sliding movement of the non-rotatable member.

The combination with a driving member and driven member, or' means for frictional engagement therebetween, presser members adapted to engage said llirictional engagement means, a .stationary member, a rotatable screw member on said stationery member, a longitudinally movable nut on said screw member, means for preventing rotation of said nut, and a rotatable thrust ring on said nut adapted to engage the presser members.

3. The combination with a driving member and driven member, of means for irictional engagement therebetween, presser members carried on said driven member adapted to engage said frictional engagement means, a stationary support, a circular flange on said stationary support provided with longitudinal slots, a rotatable screw member on said flange, a longitudinally movable nut on said screw member having lugs projecting into the slots in said circular flange, and a rotatable thrust ring on said nut adapted to engage the presser members.

4. rlhe combination of a driving member and driven member, driving disks carried by said driving member, driven disks carried by said driven member, presser mem bers carried by the driven member adapted to hold 'the driving disks and driven disks in frictional engagement, a stationary men ber, a rotatable screw member on said stationary member, a longitudinally movable nut on said screw member, means for preventing rotation of said nut, a rotatable thrust ring on said nut adapted to engage the presser members, and means for operating said screw member.

5. vThe combination of a driving shaft, a head carried on said shaft, friction driving disks carried on said head, a pulley freely rotatable on said head, friction driven disks carried on said pulley, a plate on the end olisaid pulleyscre\.vs on said plate having their inner ends abutting against the outer friction disk on said pulley, presser mem bers carried by said pulley adapted to en-`- gage the inner friction disk on-said pulley,` and means independent of said driving :haft

on said pulley, a plato on the end 'of said, pulley, meaus on .said plate forimng abut. for the outer friction disk, presser ments members carried by said pulley adapted to engage tbc inner 'friction disk, a stationary member, a rotatable screw member on said stationary member, :1 longitudinally movable nut on said screw member, n rotatable h'ust ring on said, nut 'adnptod to engage mid presser members, and 11m-oms 'for operating said sol-ow member.
